Lexus RX330 owners have reported 2 problems related to differential unit (under the power train category). The most recently reported issues are listed below.
Transmission has a hard time selecting a gear between 2nd and 3rd. It starts to go into 3rd gear then jumps out for a second and then slams back into 3rd. Usually when lightly accelerating. Very noticeable. I have taken it into the dealer 4 times and was told I may just need a new transmission!! it only has 108,000 miles on it. I have never heard of this problem with a Lexus! that and the rear differential was diagnosed as bad as well! it's like the entire drive train is garbage!! very very disappointed with Lexus and I hope they will make this right with me. I don't want to be on a trip with my family and it break down on us when I payed for reliability.

I am having serious quality problems with my 2005 Rx330. The vehicle is kept in the garage and being taken care of like a family member. I took the SUV to a Lexus dealer for routine maintenance and was told that the stearing column was leaking and need to be replaced - approximate cost $1800. I was also told the front differential was leaking and need to be replaced - cost another $1000. This is not the end! approximately six months ago my water pump failed at the middle of a busy intersection, and I had to replace my water pump, timing belt, drive belts, etc only at 65k miles - cost $1200. Why every major key components are failing so early? I drove a car made by a competitor upto 110k miles without any of these issues. Lexus/Toyota is using defective/cheap parts at the expense and safety of consumers. I would recommend starting an investigation against Lexus/Toyota for faulty steering and power train components in RX, and based on the investigation, start a recall if needed. I reached out to Lexus in the past, but they don't acknowledge any quality problems with Rx330; however, when I searched the internet, I see hundreds of owners have the same issues and they are helpless. Lexus will not do anything, and therefore, we need NHTSA's help to push Lexus to recall Rx330 steering and power train components.
